About this Unit
This unit deals with the theory and analysis of most modern antenna systems. The unit introduces basic antenna concepts - gain, radiation pattern, radiation resistance, the isotropic radiator and the Hertzian dipole. Using the Hertzian dipole concept, wire antennas are analysed in detail - the half wave dipole, the monopole, the folded dipole, and the ability to analyse a dipole of any length. Antennas arrays are studied in detail, from the basic two-element array to the general n-element case. Topics covered in this area include beamsteering, pattern shaping, and arrays with image sources to treat ground effects. The concept of self and mutual impedance is dealt with, so that parasitic elements and the Yagi-Uda array can be analysed and designed. Aperture antenna analysis is discussed in detail - Huygen's principle, horn antennas and parabolic and offset fed antenna systems. Propagation issues are discussed in detail and include power budget calculations for microwave links and satellite communications, and radar system concepts and analysis.
